* If two or more 3rd-level or higher players can't amicably decide who gets to play a disputed class, roll a die. Whomever rolls highest may play that character class. Re-roll ties. If nobody in your group has a die, ask a TD volunteer if they can get one for you.
Note: Being a higher player level than 3rd does not bestow any bonus to this roll. E.g., if a 6th-level player and a 3rd-level player are rolling-off against each other, they both have an equal chance at getting the character they want.
